- JUNEAU, Alaska (AP) - An ash cloud from a Russian volcano has dissipated after causing air traffic concerns over the weekend. Geophysicist Dave Schneider says the eruption from the Klyuchevskoy volcano that prompted the concerns ended Sunday, Alaska time. He says there were no warning messages for airborne ash Monday. Schneider says the ash cloud was spread out and extended into parts of the Yukon but at a very diffused level. He says Klyuchevskoy is an active volcano and the latest eruption was slighter bigger than what is typically seen. A spokeswoman for Alaska's largest commercial airport in Anchorage says there were no reports of big air traffic delays associated with the eruption. KTUU reported regional carrier PenAir canceled flights Saturday in Sand Point and Dutch Harbor and had delays in Cold Bay.
